Remove the size parameter from the various free functions

Since the backends can handle the allocation sizes on their own,

vmalloc: convert to alloc_ops

The final step moves the vmalloc and vmap implementation to generic code,
rewriting vmalloc and vfree as an alloc_ops implementation that is
installed by setup_vm.

This way all architectures can benefit from it just by calling setup_vm
and providing the implementation of install_page.

alloc: implement free

lib: simplify alloc_ops

Layer malloc/calloc/free/memalign over a basic allocator.
The implementation of high-level routines remains the basic one
from before, but the callback interface is reduced to a single
function. Since alloc.c now contains the physical address allocator
only, rename it.

pci: Make all ones invalid translate address

Introduce lib/alloc

alloc supplies three ingredients to the test framework that are all
related to the support of dynamic memory allocation.

The first is a set of alloc function wrappers for malloc and its
friends. Using wrappers allows test code and common code to use the
same interface for memory allocation at all stages, even though the
implementations may change with the stage, e.g. pre/post paging.

The second is a set of implementations for the alloc function
interfaces. These implementations are named early_*, as they can be
used almost immediately by the test framework.

The third is a very simple physical memory allocator, which the
early_* alloc functions build on.
